I need help to write the code to have two pulse outputs which will turn-up and Down Rpms on the Digital DC Drive controlled by one input on the mocro. I saw Schematic with Microcontroller interface mode, which has two pulse outputs. I have a little pump with pressure switch NC/NO. I would like the DC Motor rise the RPMs up to certain pressure and stay there oscilating up/down follow the signal from that Press. switch. Thanks, Peter.
